Electrolyte disorders are diseases in which the amounts of sodium, potassium, and chloride in the body’s fluids are not within the normal range, causing the balance of the body’s internal environment to be disrupted. Depending on the type of electrolyte, the symptoms include nausea, vomiting, thirst, oliguria, change in mental state and abnormal sensation. 1. Hypokalemia: If a large amount of body fluids are lost due to diarrhea, extensive burns, etc., hypokalemia will occur. Low blood potassium causes electrolyte disorders, which can be manifested as nausea, vomiting, dizziness, fatigue, and muscle weakness. 2. Hypernatremia: If the serum sodium concentration is too high due to high fever, massive dehydration, renal failure, etc., which causes electrolyte disorder and leads to hypernatremia, there will be symptoms of thirst and oliguria. 3. Hyponatremia: If too much diuretics are used, resulting in the loss of sodium ions in the body, leading to electrolyte disorders, there may be hyponatremia, which may be manifested as altered mental state, blurred consciousness, drowsiness, etc.. In addition, electrolyte disorders also have symptoms such as decreased blood pressure, sensory abnormalities, etc. If the above symptoms occur, it is recommended to go to a regular hospital in a timely manner and follow the doctor’s instructions for standardized diagnosis and treatment.
